Improvement in molding water-traps



UNITED STATES PATENT @r1-ICEC JAMES ALLEN LOYE, OF NEW YORK, N. Y.

IMPROVEMENT IN MOLDING WATER-TRAPS.

Spccitication forming part of Letters Patent No. 25,572, dated September 727, 1859. I

To all whom, it may concern:

Be it known that I, JAirEs ALLEN LowE, of the city, county, aud State of New York, have invented a new and useful Improvement in Molds for the Manufacturing of Plumbers7 Traps; and l do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference made thereon.

Figure lis a View of half a mold for a double S-trap, with the core lying in it. Fig. 2 is a longitudinal section of the core through the parting of the mold. Fig. 3 is a cross-section of core through red line. Fig. et is a cross-section of mold and core through red line. Figs. 5, 6, 7 are details of pieces 7L 71. C C L L.

In plumbing-work it is necessary,where connections are made with sewers or sinks, to guard against eftluvia rising through the pipes into the house. It is donc by placing what is termed by plumbers a trap in the pipe, which is some peculiar turn in the pipe by which the lower part of the turn is always full of water, through which the effiuvia cannot rise.

The present manner of constructing traps is to take two pieces of sheet-lead, bend them over an iron form or otherwise, and iit them and solder them together, and as the solder is softer than lead the trap must be weaker in the seam than elsewhere, also when formed the sheet-lead is thinner in the bend,the place where the most strength is required, when by casting them these difficulties are completely obviated, not only making the trap equal in strength all over, or even thicker in certain parts, if required, but also being a saving in labor as well as in the consumption of solder; but in casting, the traps being such peculiar shape, it is necessary to have a core that can be drawn without injury to the trap,which is so easily bent that sand cores cannot be used, but by constructing a metal core iu the following manner it can be drawn easily without injury to the trap. First turn a metal ring whose section will show a square with dovetails on all sides, like those shown in Fig. 3. Then turn other rings from which to make the pieces C C, also h h and L. Then cut a piece out of the first ring large enough to slide all the other pieces onto their places, which,when all. on, will form a circle, which must then be turned round, and now removing/[he outside pieces cut from the first ring the six plugs b b, shown in the drawings. Then join three together with wire eyes, so they will form a circle or straight line with ease, to one end of which attach a wire or chain sufficiently long to reach out of the straight part of the trap. Then placing the outside pieces again upon the plugs, so as to form two half-circles, into one end of each chase a screw as small as the square wi l permit, into which it the hollow cylinder a, upon which shrink the collar D, and let it be shouldered down far enough on the outside pieces to press them rml y against the screw on the cylinder. This gives us the core in two pieces,and now by fitting the center joint with short steady-pins,and by screwing one half into a mold with long bearings, as shown in Fig. l, and, drawing the other half iirmly against it, it will tightly close all the cross-joints of the core, while the' dovetails ou the plugs will hold the longitudinal joints equally tight if well fitted. Now close the mold, and it is ready for casting. After casting, unscrew the hollow cylinders, draw them out, also the plugs, by means of the chain or wire attached to them, and all that remain are the outside pieces, which can be drawn, (by metal hooks the ends of which are fitted into holes bored ou the inside of said pieces) leaving a perfect trap.

What Iclaim as my invention, and desire to secure by Letters Patent, is

The application of ametallic core, constructed and operating, substantially as herein described, to east water-traps.

JAMES ALLEN LOVE.
